우리나라 에너지소비 분해분석 연구에 대한 고찰

초록

A decomposition analysis for energy consumption is useful for a demand analysis and energy policy since it can capture the causes of the changes in energy use by industrial structure and energy intensity. After introducing the Refined Laspeyres and log-mean Divisia index methods which satisfy the ideal decomposition conditions, there have been numerous studies using those methods including Korea. However, there is a doubt about the consistency in the decomposition analysis because the analysis results varied by study periods, data, and methods. In this perspective, this paper thoroughly reviews the decomposition studies for energy consumption in Korea and then discusses theoretical and empirical issues of an energy decomposition analysis. As results, a guide by index and structural decomposition, log-mean and arithmetic-mean, decomposition factors, primary and final energy, and degree of aggregation is proposed.
